LEZYNE HV Bicycle Hand Pump, High Volume 90 PSI, Presta & Schrader Compatible, Compact Bike Pump

This pump filled my 26"x2.125" tube in less than 100 strokes. Works like a charm, is well built, and is wonderfully compact.

I have not had the chance to use the pump (medium version) to fix a flat in the field, but I did test it in my garage. The schrader and presta connections seem solid. Of course such a small device is going to require LOTS of pumping to fill a tire depending on 1) the tire volume and 2) the final pressure you desire. I have 406 (20") and 559 (26") tires on my trike, and I will accept the occasional workout given its small size, weight and solid connection to my tubes. Time will tell if I am correct in my assessment.This pump appears to be the earlier version of the "Drive HV" series. The newer is the "Grip Drive HV" which has knurling on the handle. This model is cheaper and I would think works just as well.

too large

The flexible hose unscrews from within the pump and screws onto the other end as either Presta or Schrader. Pumps enough volume of air to fill a road bike tire, and with a bit of extra effort enough air for a mountain bike. Reliable, yet light weight.

Great pump, works great and I like the flexible hose design. The only reason I can't give it 5 stars is that the hose rattles beyond belief inside the pump even when stored in a pack.

This micro pump is a beast. Fits perfectly in my hip pack and delivers every time. I find that threading the inner floppy tube onto the valve first, and then attaching the main pump works best for me. The size of this thing makes it perfect. You get what you pay for; and might as well invest in quality products for the things that are important to you (mountain biking)!

Mountain bike, 26 x 2.35 tires.I don't know what they were doing in the middle of nowhere, but ran over a strip of construction staples. Luckily some picnic tables nearby, so "field shop" set up. I've had a lot of different pumps over the years, and this one is amazingly effective for me. I've come to really despise those "clamp on" attachments. This one screws onto the presta valve, apparently with a one-way valve built in. Solid connection, no frustrating leakage, doesn't pop off, etc. I was pleasantly surprised how quickly I was able to get the tire back into a useable pressure level. Pump got a little warm in the process, but that's just physics, shows how well it is compressing the air.Would definitely buy this again and suggest it to anyone looking for a nice effective compact pump.

This does what it's supposed to do. It's made of quality materials, it inflates, it attaches to the bike easily and it looks good (unobtrusive). I expect it to last for years. However, be aware that it takes (me) 150 pumps to get my 29er tube to a ride-able pressure (firm, but shy of the 50psi I prefer). That's a forearm workout, for sure! So much for "HV" (high volume). I'm considering carrying cartridges again as the go-to means of inflation and save the pump for when I'm out of cartridges (or save it for when friends have a flat!). Also, it rubs on the bike's frame and I need to put some frame tape there to protect the paint. Maybe that's more a function of my wide Trek frame, but it rubs just the same.

ottima per la mtb per la leggerezza e il volume

Pumpen påstår sig vara abs, men det ska stå på slangen också. Slangen ska också ha en tryckknapp på prestasidan. Säkert bra pump, men tänker inte rekommendera en felaktig vara.

Great little pump that is far easier to use than others that connect directly to the wheel valve. The hose gives you some freedom of movement.I've got very big hands and this pump is a decent thickness to provide a good level of airflow and easy to grip compared to other tiny pumps with smaller diameter and fiddly handles etc

Compattezza e buoni materiali, ho provato a gonfiare le gomme della mtb 29 e sicuramente fa il suo dovere, da portarsi sempre con si quando si esce.

使いやすい。軽いし目立たない。これがないといざって時に本当に困る。
